Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Python dataclass equivalent
This library https://github.com/plumatic/plumbing, a predecessor of spec, has variants of defn and fn that allow you to specify the schema inline, sort of similar to type hints.

Show HN: Hamilton, a Microframework for Creating Dataframes
This reminds me a bit of a Clojure library called Plumbing (formerly Graph): https://github.com/plumatic/plumbing. It also let you create a DAG for structured computation. It was used for a web service, at that time.

Java 21: What’s New?
When type checking is needed, I find the Truss library* does the trick quite well.
As for the syntax, there is very little, which can make it a harder lift but once you have the hang of it you won't deal with the issues identified in the parent comment.

Tired by the dynamicism
I use truss extensively throughout my code to prevent those types of errors.

Python dataclass equivalent
I haven't tried it myself. I generally just use truss for runtime constraint checking. I use a modified version that integrates scope-capture. And malli validation for more complex cases, but I try to limit that. For me it is better to validate individual attributes as needed, vs validating an entire "type"/collection of attributes. So each function only cares about the attributes that it needs, and validates only as needed.

Love Clojure, challenged by discoverability
Use assertions for all data requirements inside functions - I use a modified version of https://github.com/ptaoussanis/truss to ensure that I never get NullReference exceptions, and this also helps make functions more self-documenting. Also use this to assert return data.
What are some alternatives?
datascript - Immutable database and Datalog query engine for Clojure, ClojureScript and JS
portal - A clojure tool to navigate through your data.
defn-spec - Add function args and return Spec checking via assertions
scope-capture - Project your Clojure(Script) REPL into the same context as your code when it ran
hamilton - A scalable general purpose micro-framework for defining dataflows. THIS REPOSITORY HAS BEEN MOVED TO www.github.com/dagworks-inc/hamilton
spec-tools - Clojure(Script) tools for clojure.spec
ghostwheel - Hassle-free inline clojure.spec with semi-automatic generative testing and side effect detection
Dask - Parallel computing with task scheduling
malli - High-performance data-driven data specification library for Clojure/Script.
